Doors and Windows

Millcroft Windows

Millcroft Windows are extruded by a Canadian-owned and operated manufacturer that takes pride in its high calibre, state-of-the-art manufacturing equipment. The know-how of a management team with previous experience in the window and marketing industries is enforced by staff that are established industry professionals.

Forming relationships with trusted suppliers, such as Cardinal Glass Industries Inc., expedites the manufacturing process via their dedication and support, whenever required. Similarly, Millcroft Windows and our suppliers are devoted to all customer care after-sales service concerns or inquiries.

To complement our services, we employ the best installers with over 30 years in the business. They are honest, hard working, clean, friendly, with an acute attention to detail. If there are any issues, our lead installer will be available to address them within 24 hours. 

Canadian Weather Extremes

Our windows are designed for Canadian weather extremes — from bitter cold to scorching hot conditions — and are validated by CSA and are Energy Star approved for all three North American weather zones. All of our vinyl windows meet strict technical specifications for energy performance — they are all tested, certified, inspected carefully before being properly packaged for delivery to our client's job sites.

Rigorous Quality Control

All of our window profiles go through rigorous quality control testing, every step of the way. The journey starts with the formation of extrusions that adhere to drawing specifications, followed by corner weld, drainage, and physical testing of each window. Quality control is executed to meet the highest standards, which explains why servicing is rarely required.

With virtually no recalls, our customers can rest assured that they will receive a high-end product with limited issues. In turn, consumer confidence leads to the recommendation of our windows to family and friends—the ultimate measure of customer satisfaction.


With sculpted proportioned lines, our vinyl windows offer the sophisticated elegance of finely crafted wood windows. These contoured surfaces play with the available light, finding attractive accents while eliminating the harsh reflected glare of flat-surfaced windows.

Be assured that you will enjoy your windows from Millcroft Windows & Doors for many many years to come!


Our triple pane windows can be customized including features such as pewter grilles, arched top, multicolour (for example a white interior with a black exterior). At Millcroft Windows, we can design your windows in most styles, colors, and shapes.

Energy Star

Our vinyl windows are certified high performance Energy Star® windows and are energy efficient. Energy Star® products can save you up to 16% on your energy bills. Millcroft Windows can balance your winter heating comfort and cost savings while also greatly reducing the common problems of solar heat while letting in the beautiful daylight.



Millcroft Windows uses vinyl extrusions made of 100% Virgin PolyVinyl Chloride (PVC) powder, and quality lead-free heat and UV stabilising additives. The choice of stabiliser largely depends on the particular end-application, and Millcroft Windows are made to withstand the often cold climate of the GTA.



We want to ensure that your sealed glass units were the best in the world. It’s as simple as that. Our windows feature sealed units made directly by highly reputable companies such as Guardian and Cardinal IG, North America’s leading manufacturers of premium LowE glass coatings.



Our vinyl windows have the highest rating for successfully resisting forced entry, exceeding the highest Canadian standards, withstanding forces up to 300 lbs. Sleep more securely and enjoy the greater peace of mind that comes with our superior security window.
